Sounds to me that you will be OK now. The TDCI 1800 gives no warning on the dashboard for low fuel pressure, it just will not start, then try again later and off she goes as if nothings wrong.If you have a lap top you can buy a simple OBD cable like the ELM on ebay. You can then check these things out for yourself.

I hope it is OK now, I have stopped and started a few times now and its had 30-60 mins rest before I tried it again. But it did this yesterday and started this morning in freezing temperatures after being stood over night and got me to wales.

I won't get the cable until next week and would have to borrow a laptop but I think I may order 1 at weekend if it still has issues.

Yes he checked it and said it was 18 but the RAC man never said anything about it. The AA man said it was the pump and a pin had snapped so I was going no where and he wasn't even pointing to the pump, he was pointing to the spider shaped rail that files the injectors, point is if it was gone then how have I done 200+ miles since.

I just wish it was sorted as its causing issues with work and I am debating on just selling it now.

I use the ELM 327 Interface which I bought on ebay. You will need a program for the computer which has to be I think a windows machine. The program I use is Easyobd. You down load for free the simple version ( V2) to make sure it works. Once you prove it can connect OK to your car you pay a small license fee and upgrade on line( V3) to increase functionality. It works fine on my laptop and I have connected to various cars.
It tells you such things as the temperature of the coolant, the Inlet boost air pressure and temperature, fuel flow and pressure, alternator output and of course the sensor performance and any stored engine fault codes. It can read a heck of a lot more but the Ford Diesel is quite a simple car really. You can then go online and see what the warning code relates to ( there is a list of Ford codes). Frankly you need this sort of device to diagnose faults on modern cars as its all electronic these days. All modern cars have obd sockets on them, the Fords is underneath the steering wheel to the right. You cannot miss it.

I am thinking one of those devices may become useful but my machine has been on computer 3 times and hasn't shown a single fault code.

I went out before to try start it and it started, I really don't want to have to pay a lot for repairs or sell my car. I do too many miles to maintain a new car so really need to get another 2 years out of my focus

No its a mechanical pump on the 1800 situated left front on the engine. The other thing worth thinking about is the fuel pressure sensor that gives the signal to the ECU. Thats why I say you need to connect up when running to check the pressure it should be around 1600 bar. Much less and she wont start. I wonder what sort of guy your AA man was!!!

A sensor will certainly be cheaper but you need to find the fault before throwing money about. How many miles has this car done? Anyway, before you get involved with rocket science lets see if a filter air leak or air-locking has been the problem. If all else fails you could have a talk with your Ford service agent if you still have problems, though they charge £80 to do a test.
